Y CHARLES lD. ROBERTS, OF FAIRFIELD, ILLINOIS, ASSIGNOR OF ONE-HALF HIS RIGHT TO WALTER H. MAXWELL, OF SAME PLACE.

`IMPROVEMENT IN CLOTHES-POUNDERS.

Specification forming part of Letters Patent No. 217,153, dated July 1, 1879; application filed April 22, 1879.

, lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and luse the same, reference being had to theaccompanying drawings,v and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a bottom view. Fig. 2 is the plan of a vertical section through m The object of my invention is to provide, in a clothes-pounder, a continuous spiral partitition `extending to the circumference, so as to obtain an even pressure 'and suction uover the whole surface ofthe bottom of the pounder.

My invention consists of the continuons pirce of sheet metal B, connected with the diaphragm E, commencing at the center, and spirally bent until near the circumference, when it makes' the shorter curve C, then continuing and forming the cylindrical cup A. The short curve C is formed so there will be no narrow crevices for dirt to collect in, and also that the pounder can be easily dried and cleaned.

To the top` of the diaphragm E is attached the conical shell H and handle-socket D, the handle-socket extending.;` through the apex of the cone H, and being attached thereto.

In using the pounder, it is alternately pressed upon and lifted from the clothes., which are to be soaped and placed in suflicient water to work easily. Thus it first makes a pneumatic pressure, which drives the water and dirt out of the clot-hes, and when withdrawn the suction `loosens the clothes and lls them with water, preparing them for the next down pressure.

What I claim as new, and desire to secure by Letters Patent, is

In a clothes-pounder, a continuous strip of sheet metal spirally bent to form a continuous partition, B, with a shorter bend at C, and continuing and forming' the cylindrical cup A, in combination with the diaphragm E, substantially as set forth. e

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

CHARLES D. ROBERTS.
